I finally have a 2003 996 tt x50. I am going to modify. I will Start with an exhaust and a air intake system. O I am thinkin B&B or fabspeed for the exhaust. The air intake I have no clue. (Please help)

 

Pass on the B&B. Do a search on exhaust.

 

There's the best and then the rest...

 

I don't know if I'd touch the intake. I'd go with ECU reprogram first and then an exhaust.

 

I would go with Cargraphic, FVD, Europipe (any of the europeans) and the Evo V flow intake, i havent had any issues with mine what so ever!

 

+ 1 Zippy,

I have had my Europipe on for 3 weeks and it is the best mod to date, Period!

I have a TechArt - been great for 30K+ miles - other turbo mods included.

 

I am in the same position you are in, just starting the mods. Here's my list in order of installation.
1. Revo flash
2. FVD sport exhaust
3. K&N Filter
4. FVD plenum
With these mods you're hovering around 500hp. I have been told by SEVERAL technicians from both Porsche and the independents to NOT, repeat NOT change the airbox. Stick with the stock box and change the filter to something that flows better.

 

exhaust sounds are very subjective. listen, pick a few then go for the one with the best build quality. you get what you pay for more times than not.

 

+1 for Europipe! I'm a VERY happy camper here. Its just state-of-the-art for those who don't compromise quality.
